Steps of Cellular Respiration

Glycolysis, Link Reaction, Citric Acid Cycle, Electron Transport Chain

Glycolysis

-Happens in cytoplasm

-No oxygen needed (ANAEROBIC)

-Produces

---2 pyruvate

---2 NADH

---2 ATP (net; use 2 at start)

Multiple Choice

Where does glycolysis take place?

• Cristae

• Cytoplasm

• Matrix

• Chloroplast

Multiple Choice

Glycolysis is considered anaerobic. What does anaerobic mean?

• No oxygen is needed to the reaction to occur

• Oxygen is needed for the reaction to occur

Multiple Choice

What is glucose broken down into?

• Pyruvate

• Pizza

• H2O

• ATP

Link Reaction

-Pyruvate enters Mitochondria

-1 CO2 is given off

-1 NADH produced

-CoA takes 2 carbon to OAA

-REPEAT for 2nd pyruvate

Multiple Select

What are the products of the link reaction?

• Pyruvate

• CO2

• H20

• NADH

Multiple Choice

How many carbons does the molecule at the end of the link reaction contain?

• 6

• 3

• 2

• 1

Citric Acid Cycle

-Occurs in Matrix

-OAA binds to 2 carbon from link

-2 CO2 released

-3 NADH produced

-1 ATP produced

-1 FADH2 produced
